I had the transmission of my 1993 Grand Am rebuilt 14,000 miles ago. Before the rebuild, the TCC clutch solenoid would not disengage. After the rebuild, the solenoid would engage from the point the engine reached 100 degrees until approximately 120-130 degrees. Any ideas why this would be happening?

This is normal, GM cars are programmed to lock convertor up after engine has reached operating temp. and at a certain speed.
